You are given three integers a, b, c (1 ≤ a, b, c ≤ 10⁹). Compute a⋅b/c, with an absolute precision of 10⁻⁶.

The first and only line of input contains the three integers a, b, c separated by a single space.

Output a single floating point number. It must differ from a⋅b/c by at most 10⁻⁶ in absolute value, i.e., it should obey |x−a⋅b/c| ≤ 10⁻⁶.

• 1 ≤ a, b, c ≤ 10

• 1 ≤ a, b, c ≤ 10000

• 1 ≤ a, b ≤ 10⁹, c=1

• 1 ≤ a, b, c ≤ 10⁹
